For a Houston SaaS company, an Astro website will almost always load faster, pass Core Web Vitals more often, and carry a far smaller security surface than a site built on WordPress — and it costs less to run over time. WordPress is the most popular CMS on earth for good reasons: it’s flexible, familiar, and endlessly extensible. But that same plugin-driven flexibility is exactly what makes it heavy, slow, and a maintenance liability for a software company whose marketing site has one job — turn expensive traffic into free trials and demos.
This is the honest, revenue-focused comparison: what each platform actually is, how they score on the metrics that decide MRR (page speed, Core Web Vitals, SEO/AEO), why WordPress’s plugin ecosystem is a hidden cost, and the exact setup we deploy for Houston SaaS teams.

The short answer
If your website’s job is to convert paid traffic into trials and demos for a software product, build it on Astro. If your site is a content-heavy blog run by non-technical editors who need a familiar dashboard and a specific WordPress plugin you can’t live without, WordPress can be the pragmatic choice — it’s the default for a reason.
The reason the default is wrong for most SaaS comes down to architecture. A WordPress site assembles each page on a server from PHP, a theme, and a stack of third-party plugins, then ships a heavy payload to the browser. An Astro site renders to static HTML at build time, ships almost zero JavaScript by default, and serves from a global edge network. On the metrics Google and your buyers actually measure — load time, Core Web Vitals, and the size of your security surface — that difference is not subtle. It shows up directly in conversion rate, which for a SaaS funnel is the same as showing up in customer acquisition cost.
Why website speed decides revenue for SaaS
Speed is not a vanity metric. It is the first conversion step, and the data has been remarkably consistent for a decade.
Google’s mobile benchmark research, built on more than 900,000 landing pages, found that as page load time goes from 1 second to 3 seconds, the probability of a bounce increases 32% — and from 1 second to 5 seconds it jumps 90% (Think with Google, 2017). Google has separately reported that 53% of mobile visitors abandon a site that takes longer than three seconds to load (Google, via Marketing Dive).
Portent’s analysis of over 100 million pageviews put a number on the revenue impact: a website that loads in 1 second converts roughly three times better than one that loads in 5 seconds, with conversion falling steadily for every additional second of load time (Portent, 2022). For a SaaS company, that’s the difference between a healthy trial funnel and a leaky one.
The compounding effect is the part founders underrate. Deloitte’s Milliseconds Make Millions study, run with Google, found that a 0.1-second improvement in mobile load time lifted retail conversions by 8.4%, consumer spend by 9.2%, and travel conversions by 10.1% (Deloitte / Think with Google, 2020). Your CAC does not care whether the leak is at the ad, the landing page, or the trial form — every fraction of a second of front-door latency is budget you already spent and then lost.
What a WordPress website actually is
Let’s be precise and fair. WordPress powers roughly 41% of all websites and about 59% of the CMS market (W3Techs, 2026) — it is the most successful publishing platform ever built. It’s flexible, has an enormous plugin and theme ecosystem, and any freelancer in Houston can maintain it.
But as a marketing website for a software company, its architecture carries structural costs:
- Every page is assembled at request time. WordPress runs PHP, loads a theme, and executes a stack of plugins to build each page — then ships a heavy result. That’s the opposite of what Core Web Vitals reward.
- Speed depends on plugins you don’t control. A typical business site runs dozens of third-party plugins, each adding scripts, styles, and database queries. The site is only as fast as its slowest plugin.
- It’s a maintenance and security surface. Core, theme, and every plugin need constant updates, or the site drifts toward breakage and vulnerability (more on this below).
- Real speed requires paid tooling. Getting WordPress genuinely fast usually means premium managed hosting, a caching plugin, a CDN, and image optimization — cost and complexity stacked on top of the base build.
None of that makes WordPress bad. It makes it the wrong layer for the one page type where speed, SEO, and security are the whole game.
What an Astro website is (and why it’s fast)
Astro is a modern web framework built on a simple idea: ship HTML, not JavaScript. Its “islands architecture” renders your pages to static HTML at build time and hydrates only the genuinely interactive pieces (a chat widget, a calculator), leaving everything else as fast, plain markup served from the edge.
The result shows up in real-world field data. In Astro’s 2023 Web Framework Performance Report — built on Chrome UX Report and HTTP Archive data — Astro was the only JavaScript framework where more than half of tracked sites passed Google’s Core Web Vitals assessment, against an all-sites average of roughly 40.5% (Astro, 2023). More recent HTTP Archive analysis reported by Search Engine Journal found the median Astro page weighs about 1.65 MB versus 2.63 MB for WordPress, with Astro origins passing Core Web Vitals at a meaningfully higher rate (Search Engine Journal, 2026).
That is the whole thesis of our Get a Website service: we build on Astro, serve from Cloudflare’s global edge, and guarantee a 90+ Google PageSpeed score (often a perfect 100) on both mobile and desktop — with no plugin bloat to slow it back down.
Astro vs WordPress: the head-to-head
Here is the comparison the way we walk SaaS founders through it. WordPress numbers reflect a typical plugin-driven business build; a hand-tuned, minimally-plugged WordPress site can do better, but that is not what most teams actually run.
| Plan | Astro Website (ours) recommended | WordPress Website |
|---|---|---|
| Price | $497 one-time + $97/mo | Build + hosting + plugins + upkeep |
| Feature 1 | Google PageSpeed: 90-100 (guaranteed) | Google PageSpeed: often 40-70 on a plugin build |
| Feature 2 | Ships almost zero JavaScript by default | Ships heavy JavaScript, CSS, and PHP output |
| Feature 3 | Static-first HTML from Cloudflare's global edge | Pages assembled per request on the server |
| Feature 4 | ~1.65 MB median page weight | ~2.63 MB median page weight |
| Feature 5 | No plugins, no PHP, no server runtime to exploit | Dozens of plugins = a real attack surface |
| Feature 6 | Full control of meta, JSON-LD schema, canonical | Meta/schema control depends on SEO plugins |
| Feature 7 | llms.txt + AEO/GEO built for AI answer engines | No native llms.txt; AEO/GEO is manual |
| Feature 8 | Managed hosting, domain, SSL, updates included | You (or a dev) own updates, backups, security |
| Feature 9 | Connects to GoHighLevel CRM + AI chat widget | Integrations via plugins of varying quality |
| Feature 10 | No caching plugins or CDN add-ons to buy | Speed needs paid caching, CDN, and optimization |
| Get an Astro site | Prefer a custom build? |
The plugin problem: security and maintenance
This is where the comparison stops being about milliseconds and starts being about risk. WordPress’s greatest strength — its plugin ecosystem — is also its biggest liability.
Patchstack, which tracks WordPress security, reported roughly 8,000 new vulnerabilities across the WordPress ecosystem in 2024, a 34% jump over 2023 (Patchstack, 2024). The crucial detail for a SaaS operator: 96% of those vulnerabilities came from plugins, not WordPress core — themes accounted for about 4%, and core itself for a fraction of a percent. Roughly 43% were exploitable without any authentication, and more than half of the reported plugin developers had not shipped a patch before the flaw was disclosed publicly. Independent reporting corroborated the scale — “8,000 new WordPress vulnerabilities reported in 2024” (SecurityWeek).
An Astro marketing site sidesteps this category almost entirely. There is no PHP executing on a server, no database queried on every request, and no plugin ecosystem to keep patched. The site is pre-built static HTML on a CDN — there is simply far less to attack. For a software company, where a defaced or compromised marketing site is a trust catastrophe in front of technical buyers, that reduction in surface area is worth as much as the speed.
Core Web Vitals and SEO: who wins
Core Web Vitals — Largest Contentful Paint, Interaction to Next Paint, and Cumulative Layout Shift — are a confirmed input to Google’s ranking systems as part of the page experience signals (Google Search Central). They aren’t the only factor, but when two SaaS sites target the same keyword with comparable content, the faster, more stable one has a real edge — and it converts more of the traffic it earns.
Most of the web still struggles here. According to the HTTP Archive Web Almanac 2025, only about 48% of mobile sites and 56% of desktop sites had “good” Core Web Vitals (HTTP Archive, 2025). Page weight is a big part of the story, and it’s exactly where the two platforms diverge: the median WordPress page weighs about 2.63 MB versus roughly 1.65 MB for Astro (Search Engine Journal, 2026). Lighter pages paint faster, shift less, and respond quicker — the three things Core Web Vitals measure.
There’s a second SEO front that plugin-driven sites lose by default: AI answer engines. Google AI Overviews, ChatGPT, and Perplexity increasingly intercept research queries, and they favor sites with clean, crawlable HTML, valid structured data, and an llms.txt manifest. On Astro we control all three directly; on WordPress each depends on a plugin doing its job correctly. If you want the deeper playbook, we wrote it up in SaaS SEO in 2026: Rank, Get Cited, Convert Trials. And if your comparison is against a GoHighLevel-built site rather than WordPress, we covered that head-to-head in Astro vs GoHighLevel Websites.
Why this matters for a Houston SaaS company
Houston is no longer just an energy town — it’s a genuine software hub. The Greater Houston Partnership counts more than 8,800 technology firms and over 700 venture-backed startups in the region, a tech workforce of roughly 235,000, and the 12th-largest tech sector in the U.S., contributing about $28.1 billion to the local economy (Greater Houston Partnership, 2025).
Two practical consequences for a Houston SaaS company:
- Competition for high-intent search is climbing. As more local software companies and out-of-state entrants bid for category terms and “software for [Houston industry]” queries, a slow, heavy marketing site that converts at a fraction of the rate of a fast one quietly wastes acquisition budget. Front-door speed is CAC efficiency.
- Your buyers are technical and impatient. Houston’s software buyers — in energy tech, healthcare, logistics, and fintech — evaluate tools constantly. A janky, plugin-bloated site reads as a signal about the product behind it. A fast, clean site reads as competence.
Ranking for local-intent and category queries — and getting cited in the AI answers Houston buyers now ask first — rewards the technical fundamentals Astro delivers and a typical WordPress build fights against.
When WordPress is still the right call
We won’t pretend Astro wins every scenario. WordPress is the better fit when:
- You publish high volumes of content with non-technical editors who need a familiar dashboard, and editorial workflow matters more than a perfect PageSpeed score.
- You depend on a specific WordPress plugin or ecosystem — a particular membership, LMS, or WooCommerce setup — that would be expensive to rebuild.
- You already have a WordPress team maintaining it well, with disciplined updates, good hosting, and a lean plugin list.
For those jobs, WordPress’s maturity is a genuine advantage. But if your site’s primary job is converting paid traffic into SaaS trials, those advantages rarely outweigh the speed, security, and SEO gap. If your needs go beyond a marketing site into product surfaces, portals, or custom apps, that’s what our custom software team builds — and if you want to keep GoHighLevel as your CRM engine, our GHL development team wires it in.
The setup we actually recommend
The honest answer for most SaaS teams is a clean split: a fast, static Astro front door connected to the tools you already run behind it.
That’s precisely how we deliver Get a Website: an Astro build with a guaranteed 90+ PageSpeed, category SEO plus AEO/GEO, feature/use-case/location pages, an embedded AI chat widget, and a direct connection into your GoHighLevel CRM — for $497 one-time + $97/month (managed hosting, domain, SSL, and maintenance included, and the one-time fee isn’t charged until the site is live and you’re happy). Add automatic blogging — two posts a week — for $197/month total, or create and rebrand up to five sites for a $1,200 one-time fee.
Speed and security are the cheapest conversion-rate optimization you’ll ever buy — a one-time build decision that pays out on every visit, forever, without a maintenance tax. For a Houston SaaS company fighting for expensive, technical traffic, that’s not a nice-to-have.
Frequently asked questions
Is an Astro website really faster than WordPress?
In almost every real-world case, yes. Astro ships static HTML with almost no JavaScript and serves it from a global edge network, while a typical WordPress site assembles each page from PHP, a theme, and a stack of plugins before shipping a heavier payload. In field data, the median Astro page weighs about 1.65 MB versus 2.63 MB for WordPress, and Astro passes Core Web Vitals at a higher rate. We guarantee a 90+ Google PageSpeed on the Astro sites we build.
How is Astro more secure than WordPress?
By having far less to attack. Patchstack reported roughly 8,000 new WordPress-ecosystem vulnerabilities in 2024, and 96% of them came from plugins. An Astro marketing site is pre-built static HTML on a CDN — there's no PHP running on a server, no database queried per request, and no plugin ecosystem to keep patched. That removes almost the entire category of risk that plugin-driven WordPress sites carry.
Does website speed actually affect Google rankings?
It's one confirmed input. Google's page experience signals include Core Web Vitals — Largest Contentful Paint, Interaction to Next Paint, and Cumulative Layout Shift. Speed alone won't outrank far better content, but between two comparable SaaS pages targeting the same keyword, the faster, more stable one has an edge — and it converts more of the traffic it earns.
Can I keep my WordPress blog and still get a fast site?
Often, yes. A common setup is a fast Astro marketing site for your homepage, feature, pricing, and location pages — the pages where speed and SEO decide revenue — while a content team keeps publishing where it's comfortable. We can also migrate your content into the Astro build with automatic blogging so the whole site stays on one fast stack. We'll recommend the split that fits your team.
What does an Astro website from you cost, and what's included?
A single Astro site is $497 one-time plus $97/month, which covers managed Cloudflare hosting, your domain, SSL, and maintenance — and the one-time fee isn't charged until the site is live and you're happy. You get feature, use-case, and location pages, full schema/AEO/GEO, an AI chat widget, and a connection to your GoHighLevel CRM. Automatic blogging (two posts a week) is $197/month total, and up to five sites is a $1,200 one-time fee.
Why does this matter specifically for a Houston SaaS company?
Houston has become a real software hub — more than 8,800 tech firms, over 700 venture-backed startups, and the 12th-largest tech sector in the U.S. As competition for high-intent search climbs, a slow, plugin-heavy site wastes acquisition budget you already spent, and reads as a red flag to the technical buyers evaluating your product. A fast, secure Astro site turns more of that expensive traffic into trials.
